摘要 : The basic reciprocity relation for a random component was demonstrated, the reciprocity relation for a random component was introduced through the wave approach and the modal approach. The coupling between two area junction subsystems was also introduced. The hybrid FE-SEA equation was given at the last demonstration for the theoretic results. Hybrid FE-SEA model of the car was built, the radiation efficiencies of the body panels of the car were calculated, and the excitations of the powertrain mounts and body suspensions of the car were measured. The acoustic excitation of the engine cabin wa
